根据泄洪过程中库水位过程的随机微分方程,利用数值解方法,模拟了随机干扰下的库水位及其波动状况.采用相应公式计算了洪水漫越坝顶事件的概率以及库水位过程在不同时刻的样本均值.并通过比较在同样强度的随机干扰下库水位的高低状况,确定出各种泄洪方案的优劣,从而对防洪工作具有重要的指导意义.
According to the stochastic differential equation of reservoir water level in flood discharge process, the numerical solution method is used to simulate the reservoir water level and its fluctuation under random disturbance. The probability of flood event and the process of reservoir water level at different time And by comparing the level of reservoir water level under the same intensity of random disturbance, the advantages and disadvantages of various flood discharge schemes are determined, which is of great guiding significance for flood control work.
